unable to compile native unpacker

[springrider]

I am using android-ndk-r10d, under "native-unpacker " dir,
using "make" command, at first it prompts: [armeabi] Compile thumb : kisskiss <= kisskiss.c

./kisskiss.c: In function 'main':
./kisskiss.c:110:3: error: 'for' loop initial declarations are only allowed in C99 mode
   for(int i = 0; i < found; i++) {
   ^
./kisskiss.c:110:3: note: use option -std=c99 or -std=gnu99 to compile your code

then I added "LOCAL_CFLAGS += -std=c99" in Android.mk and it passed, but when I "make" again, it says:

[armeabi] Compile thumb  : kisskiss <= kisskiss.c
./kisskiss.c: In function 'peek_memory':
./kisskiss.c:341:3: warning: implicit declaration of function 'pread64' [-Wimplicit-function-declaration]
   int read = pread64(memory_file, buffer, 8, address);
   ^
[armeabi] Executable     : kisskiss
./kisskiss.c:341: error: undefined reference to 'pread64'
./kisskiss.c:378: error: undefined reference to 'pread64'
collect2: error: ld returned 1 exit status
make[1]: *** [obj/local/armeabi/kisskiss] Error 1

any suggestion?

I suggest repulling the directory and potentially using a more up to date ndk. Works fine for me on a fresh macbook which I've installed the ndk via brew;

so sorry for the late reply, I didn't know you reply so quick. will try it now and update the result.

[springrider]

yep it's the ndk version caused the problem. I used brew to install new version ndk and it works now, thanks alot for your time!

[strazzere]

Not a problem, glad it worked!
